Lecture Notes and Tutorials
Notes from PhysicsLAB by Catherine H. Colwell
These notes contain detailed explanations of background material, annotated diagrams and illustrations, and solved examples.
  Interference
  Interference and Diffraction Patterns
  Slit Patterns
  Thin Film Interference

Simulations
Physics Simulation Library
Each simulation includes an audio introduction and general directions. These simulations are very well designed, and each experiment gives the opportunity to change the parameters, collect data, and interpret various graphs. The Interference of Light simulation is included.
